Abstract

The present invention discloses a transflective liquid crystal display panel and a liquid crystal display device comprising the same. Each pixel unit of the transflective liquid crystal display panel comprises a transmission region and a reflection region. The transflective liquid crystal display panel further comprises a conductive polarizing film layer having a first polarizing direction in the reflection region and a second polarizing direction in the transmission region.

Claims

exact text as granted — not AI-modified
The invention claimed is: 
     
       1. A transflective liquid crystal display panel, each of pixel units of the transflective liquid crystal display panel comprising a transmission region and a reflection region, wherein,
 the transflective liquid crystal display panel further comprises a conductive polarizing film layer, the conductive polarizing film layer has a first polarizing direction in the reflection region and a second polarizing direction in the transmission region. 
 
     
     
       2. The transflective liquid crystal display panel according to  claim 1 , wherein,
 a liquid crystal layer provided in the transmission region is a transmission region liquid crystal layer, and a liquid crystal layer provided in the reflection region is a reflection region liquid crystal layer, wherein the thickness of the reflection region liquid crystal layer is a half of that of the transmission region liquid crystal layer. 
 
     
     
       3. The transflective liquid crystal display panel according to  claim 1 , wherein,
 a first polarizing direction of the conductive polarizing film layer in the reflection region is 45°, and a second polarizing direction of the conductive polarizing film layer in the transmission region is 90°. 
 
     
     
       4. The transflective liquid crystal display panel according to  claim 1 , wherein,
 the conductive polarizing film layer is provided on a surface of a display side substrate of the transflective liquid crystal display panel, the surface of the display side substrate being back against a non-display side substrate of the transflective liquid crystal display panel. 
 
     
     
       5. The transflective liquid crystal display panel according to  claim 1 , wherein,
 the transflective liquid crystal display panel is an Advanced Super Dimension Switch type liquid crystal display panel. 
 
     
     
       6. A liquid crystal display device, comprising a transflective liquid crystal display panel each of pixel units of the transflective liquid crystal display panel comprising a transmission region and a reflection region, wherein,
 the transflective liquid crystal display panel further comprises a conductive polarizing film layer, the conductive polarizing film layer has a first polarizing direction in the reflection region and a second polarizing direction in the transmission region. 
 
     
     
       7. The liquid crystal display device according to  claim 6 , wherein,
 a liquid crystal layer provided in the transmission region is a transmission region liquid crystal layer, and a liquid crystal layer provided in the reflection region is a reflection region liquid crystal layer, wherein the thickness of the reflection region liquid crystal layer is a half of that of the transmission region liquid crystal layer. 
 
     
     
       8. The liquid crystal display device according to  claim 6 , wherein,
 a first polarizing direction of the conductive polarizing film layer in the reflection region is 45°, and a second polarizing direction of the conductive polarizing film layer in the transmission region is 90°. 
 
     
     
       9. The liquid crystal display device according to  claim 6 , wherein,
 the conductive polarizing film layer is provided on a surface of a display side substrate of the transflective liquid crystal display panel, the surface of the display side substrate being back against a non-display side substrate of the transflective liquid crystal display panel. 
 
     
     
       10. The liquid crystal display device according to  claim 6 , wherein,
 the transflective liquid crystal display panel is an Advanced Super Dimension Switch type liquid crystal display panel.
